404 FUNAFUTI ATOLL. 
This species has its nearest kin in 1’. «/..,camomea, Gould, but 
differs so widely from that by contour, sculpture and exposed 
nepionic shell that a new genus seems necessary to express the 
distinction. Yet P.cinnamomea itself stands perhaps as far again 
from the type of the genus P. crenulata, Broderip, and being 
unable to offer any information on the animal of the new species, 
I am unwilling to further divide a group of which our knowledge 
is so brief. 
Scutellina of Gray (1847) being preoccupied by Scatellina of 
Agassiz (1841), Pilsbry has substituted Phenacolepas.* 
TROCHUS OBELISCUS, Gmelin. 
Pilsbry, Man. Conch. xi. 1889, p. 19, pl. ii, figs. 13, 14. 
Several specimens were taken alive in shallow water in the 
lagoon associated with J/itra episcopalis. 
Fischer quotes this from New Caledonia, Fiji, Samoa and Tonga. 
TROCHUS TUBIFERUS, Kiener. 
Pilsbry, op. ctt., p. ol, pl. vi. figs. 62, 63. 
Two living specimens were found at low water on the western 
side of the Funafuti lagoon. 
Fischert gives as the range of this species New Caledonia, 
Loyalty Islands, Upolu, Samoa, and Pilsbry adds Fiji. 
TROCHUS ATROPURPUREUS, Gould. 
Pilsbry, op. cit., p. 77, pl. xi., figs. 28-32; pl. xiii., figs. 86, 87; pl. 
xv., figs. 50, 51. 
Not uncommon as dead shells on the lagoon beach. 
Pilsbry notes this from San Christoval, Solomons, Tutuila, 
Samoa and Fiji. In this Museum are specimens from New Cale- 
donia and Tupuselei, Hood Lagoon and Milne Bay, British New 
Guinea. 
TrocHUS FASTIGIATUS, A. Adams. 
Reeve, Conch. Icon. xiii., 1861, Trochus, pl. xv., fig. 87. 
Several dead specimens from the beach of the Funafuti lagoon. 
Though described nearly half a century ago, the locality of this 
species has not hitherto been announced. I have also collected it 
at Panie, New Caledonia. 
GIBBULA CONCINNA, Dunker. 
Pilsbry, op. cit., p. 230, pl. xl., figs. 8, 9. 
A shell plentiful at Funafuti and which I also saw at Nukulailai, 
seems, though not agreeing exactly, to be nearest this. The
